I think you chose well - Magic Missile is inevitable, of course, Identify seems wise, as does Protection from Evil. Not sure about P. from Petrification, I don't think you'll need it *that* much... maybe Armor for protection when you're lower level?
Level two: Web or Stinking Cloud may be handy to disable large groups of enemies... Mirror Image, Melf's Acid Arrow and Knock were well chosen though.
Uhh..a lot of accurate archers out there? I haven't seen *that* many... besides, are you sure that enemy archers use normal (i.e. non-magical) weapons? Melf's Minute Meteors are indispensable, maybe you could use a Fireball spell too, though you could use wands for that.
Stoneskin would have been my choice as well for level 4, followed by Wizard Eye.
